7 Claims. (c 1. 141-9) This invention relates to apparatus forwashingdishes. and more particularly to improve-,

ments in a combined sink and dishwasher.

One object of this invention is to provide means i 5 for converting anordinary kitchen sink into a This object is attained by removwash waterand directs the same onto the disheswithin the sink.

' Another object of this invention is to, provide a water deflectingcanopy adapted to be pivoted above a sink and which may be readilyturned into a position overhanging the sink for the purpose ofdeflecting wash water, directed thereagainst, over \the dishes placed inthe sink bowl, the canopy being perforated and with the spaceimmediately thereabove connected to a clear water supply whereby waterfrom such supply may be sprayed over the washed dishes.

A further object is to provide means for converting an ordinary kitchensink into a dishwasher, whichis economical to manufacture,

simple to assemble and operate and'which will notin-terfer'e with theordinary function of the sink, since all the dishwater parts may beeither 35. entirely removed from the sink or moved to an Figure 1 is avertical section taken on a longitudinal plane through the center of asink having apparatus associated therewith for converting the sink intoa dishwasher in accordance with my"invention.

Referring to the drawings in detail, l0 represents the bowl of a,kitchen sink fabricated from sheet metal which is preferably of anon-corro-. sive tube such as stainless steel. The sink has a drainboardH 'on each side thereof and a riser or splash back I2 at the rear andwhich ex tends the full length of the sink. The sink bowl I0 is of theusual standard depth and is provided with the usual centrally locateddrain iii in the bottom opening thereof.

To adapt a sink of this general character for use as a mechanicaldishwasher, I secure'to the ing it has a port l! for connecting thehousing with the tank 14 and communication between the housing and thetank is controlled by a slide valve l8 having a port ll therein movableinto and out of registry with the port I! between housing It and thetank. The bottom of the tank It is also connnected'to asuitable drain Hahaving a valve llb therein for closing the drain when dishesa re to bewashed and the tank is to be filled with water. Communication betweenthe outlet of the pump and the housing I6 is also controlled by theslide valve l8 which has an opening ltgtherein' movable into-and out ofregistry with the outlet ill of the pump. Valve 18 is slidably mountedinspaced guides 20 secured in position within the housing It, and saidvalve is movedback and forth by an operating handle or lever M. Thislever is attached to 'a stub shaft 22 extending through the bottom. ofthe housing and which is provided with a pinion 23 which meshes withrack teeth 24- formed on slide valve IS. The shaft of pump It has apulley 25 secured thereto and which f is driven from a-suitable' motor,such as an electrio source of power (not'shown);

y A tube or standp'ipe 21 is removably mounted Attached to theinner wallof the standpipe 2'1- suitable manner.

in the "opening l3 of the sinkbowl win any The lower end of the tube orstandpipe 21. is flared outwardly and is provided'with perforations 28,which permitwater to flowi'rom the sink bowl to the housing I6.

is a tube 29 of smaller diameter than the diameter of'the openinglS, andwhich is spaced from the flared portion of the standpipe and is ofsuch alength that when the' s'tandpipe is positioned in the opening l3 thelower end of the tube 29 seats on the top of the slide valve l8.

. An openworkor wire basket 30 surroundslthe standpipe 2.1 andisprovidedwith rubber covered legs 3! which support the basket inspacedrelation'above the bottom of thesink bowl 10'. The top of the basket 30is formed of two con centric rings 32-33 which are covered with asuitable 'material' to prevent and reduce breakage of the dishes placedtherein.. The inner ring 33 is of somewhat larger diameter than; the

standpipe 2l s o that it is free to slide thereover. The bottom wires 35of the basket extend radiw ally and'each is provided with an upstandinglug 36 covered with rubber 'or some other soft material. These lugs actas stops or, bumpers. and permit larger: dishes, such as plat-es, toarranged in the basket in a manner so that the dishes simulate thechords of a circle. Overhanging the sink bowl is a water deflect-' ingdevice comprising an annular deflector 4U having both its center and itsedge pressed downwardly and partially covered byan annular plate likemember 4| of substantially less diameter than the diameter of thedeflector 4|. Member'fl is bolted to an ari'n42. The member 4| is ofsubstantially-concaveshapeand a space 43 is provided between thedeflector 40 and'the plate 4|, the purpose .of which will hereinafterbe. de-

' scribed. Deflector 40 is held in engagement with the plate 4| by abolt 44 which extends. throughan opening. in the depressed centralportionof the deflector and is'threadedinto an insulated handle or knob45 on the top of the arm 42. The:

rear end of the arm 42 is hinged 'to a bracket 46 secured to the backrim or flllet of the sink and the hinge is so constructedlthat the waterdeflecting member 40 may be turned from a substantially horizontalposition where it overhangs -the sink bowl to' a substantially upright.posi-' tion with the arm 42 resting against stops".

on the bracket 46 (Fig. 5); t

When the sink is to be used as a dishwasher the valve I4!) is closed andthe standpipe 21 is secured within opening l3. The basket 30 is thenplaced in position where it surrounds stand-- pipe .21 and isloaded'with soiled dishes. Water is introduced intothe sink through thefaucets 50, one of which isoonnectedto'the hotwater supply and-the otherto the cold-water supply. The water passes through the perforations 28in the flared portion of standpipe 21, into housing 16. After suflicientwashing water has been introduced into the sink bowl to fill tank l4,:(the sink proper beingempty of, water during the dishwashi-n goperation), vsufficie'ntsoap is added to produce a thick suds. Thedeflector 40 is turned toa substantially horizontal position overhangingthe sink. This movement of the deflector releases the operating handle2| 1 (as will be hereinafter described) and permits the valve memberllto be meted so as to P951 ing used- -as a. dishwasher. t v In order thatthe valve l8 may be locked against accidental displacement when thedeflector 40 is tion'its opening 19' ova the outlet. of the pump l5 andbrings its opening: ll into registry with the port H in the housing I6which permits the .water in the sink to pass into the tank. The pump I5is then started and wash water is forced 5 upwardly through the. tube 28and standpipe 21 and directed against the deflector 40, The course ofthe water striking the deflector 40 is changed thereby and directed overthe dishes in the basket 30.- The washin'g'water after leaving thedishes itroduced into .the chamber 43 between the plate 4! and the"deflector 40 and sprayed over the dishes in the basket'30- throughperforations 40a in the deflector plate 40;, Water is delivered to thechamber 43-through a pipe 52.formed integrallywith the arm 42' whichopens, at one end, intothe chamber-.43 and is connected at the other endto a flexible tube '53 leading to faucet 54 connected to asuitable'sou'rce of clear water. Thus, the. perforateddeflector plate 40acts asa spray head for directing the clear wa-- ter in the chamber -43over'the dishes in the basket. After .the dishes have been washed andrinsed, the valve bis 'opene'dand the wash water is drained from thetank and discharged through the drain pipe I4a. I

After the dishes have been washed: the deflector 40 is raised from itshorizontal position to a substantially upright position and the basket30 containing the clean dishes is lifted out of the sink bowlafterwhichthe standpipe 21 is removed, and the valve I8 is closed, thus making thesink available for use in the'ordinary manner. The. closing'of valvemember It} covers the port between the housing and tank and the outletof the pump and prevents food par- 1 ticles-and the like from passinginto the tank and pump and thus clogging the pump. Such foodparticles asmay 'get into the tank during the dlshwashing-process may be preventedfrom entering the inlet side of the pump :by cover ing. the same-withawire mesh screen'of'suitable size. (none shown). and in order that thefood particles, etc., collected in the tank l4 may be readily removedand. the tank cleans-done side of the tank is provided'with a removablea locking device l4d. v A

when the sln'k'is being used in the ordinary manner and valve I8 isclosed, water -therein may be discharged through a suitable outletopenmgl 30. formed in one corner of the sink. This outlet orifice is connectedto a drain pipe l3b which connects: it with the overflow pipe 13k: 66

for the tank l4 and sink Ill and which leadsto the drain pipe Ila."Opening 1311 15 of ordinary "construction-as shown, and is closed by theusual rubber valve plug when the sink is bein its raised position, Iprovide an extension 21a on the lever or operating handle 2| whichhas' Hopening 211 therein for receiving the down- I v 5 1o flows back-intothe-tank. l 4 where it is again- .picked'up by the pump and forcedagainst the deflector 40.

cover-14c which is held' in place on the tankb'y a projection 63 on thearm 42 and extending at right angles to that arm. From thisconstruction, it is apparent that when the deflector 40 is turned toanupright position as shown in. Fig. 5 the rod 62 is'raised, thusturning the rod 6| about its pivot and moving the portion 60 downwardlyinto the opening 21b of the operating handle 2 I.

From the foregoing description of my invention, it is apparent that Ihave provided a sink which, if desired, may be readily converted into amechanical dishwasher that is extremely simpie to assemble and easytooperate, has few parts to get out of order, and since the operatinglever 2! is locked in the position closing the valve [8 when thedeflector to is raised, is posi-' tive in operation and will notdeliverwater if the motor should he accidentally turned on when thedeflector is raised.

While I have described one embodiment of my invention, it is apparentfrom the foregoing description that certain changes, modifications,additions, omissions and subtractions may be made therein withoutdeparting from the spirit of my invention or the scope of theappendedclaims.

Having thus described my invention, what I claim as new and-desire tosecure by Letters Patout is:
